Summit 吸管蓋水壺

The straw lid seals tight enough that my kid can toss it in the lunchbox sideways without a drop leaking. Three hours later the water’s still properly cold, which is honestly all I needed from this bottle.

The vacuum insulation actually works, my son's water was still ice-cold after sitting in the car all afternoon. The straw lid locks tight enough that not a single drop leaked in his backpack.

My kid is rough on everything, but this bottle holds up and the straw lid actually stays leak-proof when we flip the nozzle closed before tossing it in the backpack. The insulation keeps water ice-cold after a full morning at the park, which is exactly what I needed for summer.
